Is it even true???
I'm pretty sure it was built by respected and experienced craftsman.

Partially, yes. Source: The White House Historical Association
Construction on the President's House began in 1792 in Washington, D.C., a new capital situated in sparsely settled region far from a major population center. The decision to place the capital on land ceded by two slave states-Virginia and Maryland-ultimately influenced the acquisition of laborers to construct its public buildings. The D.C. commissioners, charged by Congress with building the new city under the direction of the president, initially planned to import workers from Europe to meet their labor needs. However, response to recruitment was dismal and soon they turned to African American—enslaved and free—to provide the bulk of labor that built the White House, the United States Capitol, and other early government buildings.Stonemason Collen Williamson trained enslaved people on the spot at the government's quarry at Aquia, Virginia. Enslaved people quarried and cut the rough stone that was later dressed and laid by Scottish masons to erect the walls of the President's House. The slaves joined a work force that included local white laborers and artisans from Maryland and Virginia, as well as immigrants from Ireland, Scotland, and other European nations.
Yes. Slaves definitely did a lot of the work to build the White House and were also used to create the materials from which it was built. It is necessarily a bad thing to mention an historical fact.
Yes, but also they used paid workers and artisans
The artisans and craftsmen of the late 18th century were all white. Slaves may have driven the wagons to the construction site and unloaded them but white people built the white house and everything else during that time period.
